Convection Cooling System Prototype (LPNHE +OSU+Torino U.)

Actual FEE results: ~ 0.6mWatt/chNo Power cycling included yetMain problem: power dissipation from neighbours

Eudet-Memo-2007-52

Motorised 3D Table(Torino) suitable for testing Silicon sensors, pixel and

microstrips in a beam test, DUT can be moved and rotated with respect the beam

line. built in a modular way, so that it can arrange different

types of DUT, with alignment telescopes or without. 5 motors are controlled remotely via RS232, to set

positions and angles, via LabVieW application

FE Chip version 1(LPNHE+Barcelona U.) After first prototype in 180 nm technology, 4-

channel SITR-130_4 chip was designed in 130 nm and produced

The chip was fully tested both standalone and with a strip sensor attached

Based on the test results version 2 has been designed and submitted

Main features of new circuitMain features of new circuit

88 channels (1 test channel): Preamplier, shaper, sparsifier,analog pipeline (8x8 celles), 12 bits ADC

2D memory structure: 8x8/channels

Fully digital control:- Bias voltage(10 bits) and current (8 bits)- Power cycling (in optional)- Shaping time programable- Sampling frequency programable- Internal calibration- Sparsifier's threshold programable per channel - Event tag and time tag generation

24

Forward tracker prototype Detector modules equipped with special

alignment sensors IR Laser alignment will be performed These modules will be tested at October

CERN beam test this deliverable would benefit from

postponing the deadline from M36 to M42

24th Sept-8th October test beam will study

performance of new HPK alignment sensors

These are “standard” sensors with an Al-free

window in the backside (ohmic contact)

IR beam pseudotrack can be used to traverse

several sensors

Ohmic side:

Alignment

passage

Particle beam

IR beam

Alignment-friendly

sensors

Standard sensor

Standard sensor

Alignment prototype on beam

1) Show that the performance of the alignment friendly sensors is the same as

the standard ones

2) Compare track reconstructed geometry to IR beam reconstructed geometry

3) Shift only central alignment sensor and compare reconstructed

displacement with particle beam

and with IR beamParticle beam

IR beam

Alignment-friendly

sensors

IR bandpass filter

The same setup employed in the

test beam can be used as well as

an alignment monitor. We just need

an IR transparent window in the

front side of the cage (it can be a

small bandpass filter).

Silicon tracking infrastructure Various facilities needed for successful

detector testing Cooling Alignment 3D motion Tracking

Integration of the other deliverables Could be together by M36, but would be of

better quality if postponed to M48

LP-TPC: Silicon Envelope(HEPHY, IEKP Karlsruhe)

TPC Magnet

Beam

Rails Module

four silicon modules will be installed:- two in front and two behind the

TPC, with respect to the e--beam two independent support structures are needed

- on each side: one horizontal module consisting of two daisy-chained sensors

and one vertical module consisting of one sensor

movable support system is needed because it must be possible to scan the TPC

- the TPC and the magnet will move relative to the beam

- the sensors have to stay inside the beam line

June: Hamamatsu test structures Sep-Oct: Hamamatsu alignment sensors

2009 March: DESY, FE chip+HPK sensors Later: CERN (HE beam) Later: FNAL (combined)

Conclusions Past deliverables: all completed 4 M36 deliverables:

2 almost complete Other 2: SITRA working with full speed

towards completion, but postponing the deadline to M42 or M48 would allow higher quality results
